Experimental descriptions of Aβ oligomers (oli-Aβs) assembled on surfaces as compared with Aβ monomers (mono-Aβs) are crucial to understanding changes in chemical reactivity. Here, we fabricated Aβ molecular junctions between linker molecular layered electrodes using different Aβ segments and report that electron transport pathways changed from asymmetric hopping across monomeric Aβ junctions to symmetric tunneling across oligomeric Aβ junctions.
